21916-2 Inputting a Recursion Formula andGenerating a TableExample 1 To input a n+1 = 2an + 1 and generate a table of values as thevalue of n change from 1 to 6Make a1 = 1.1. Specify the recursion formula type as linear recursion between two terms andthen input the formula.c4(n, an···) 2(a n) +b2. Press w5 (RANG) to display the table range setting screen, which containsthe following items.• {a0}/{a1} ... setting of value for {a0 (b0)}/{a1 (b1 )}The table range settings specify the conditions that control the value of variable nin the recursion formula, and the initial term of the numeric value table. You shouldalso specify a starting point for the pointer when drawing a convergence/diver-gence graph (WEB graph) for a formula for linear recursion between two terms.Start ................ Starting value of variable nEnd ................. Ending value of variable na0, b0 ............... Value of 0th term a0/b0 (a1 , b1 .... Value of 1st term a1 /b1 )a nStr, bnStr ...... Pointer starting point for convergence/divergence graph(WEB graph)• The value of variable n increments by 1.3. Specify the range of the table.2(a1 )bwgwbw4. Display the table of the recursion formula. At this time, a menu of tablefunctions appears at the bottom of the screen.J6(TABL)Currently selected cell (up to six digits)Value in currently highlighted cellP.225
